到上一教程为止，我们已经建立好一个博客的框架，但是只有一个主页，我们在网络上看到的博客，一般首页是一个文章页表，并显示文章的部分内容，点击文章标题就会跳转到文章详细页面。下面我们就来实现这一功能。
现在修改my_blog/article/views.py代码，在文件中添加如下的代码：
from django.http import Http404
def detail(request, id):
try:
post = Article.objects.get(id=str( ...

一、了解Django程序的逻辑
1、先来说说我们上网时，网页是如何呈现在我们屏幕上的：
通过浏览器向服务器发出request请求->从服务器获取数据->服务器处理数据->把网页呈现出来。
Django中的url设置相当于客户端向服务器发出request请求的入口, 并用来指明要调用的程序逻辑
Django中的views用来处理程序逻辑, 然后呈现到template(一般为GET方法, POST方法略有不同)
Django中的template一般为html+C ...

一、创建models
打开my_blog/article/models.py文件，将下面的代码添加到文件的末尾:
class Article(models.Model) :
title = models.CharField(max_length = 100) #博客题目
category = models.CharField(max_length = 50, blank = True) #博客标签
date_time = models.DateTimeField(auto_now_add = True) #博客日期
content = models.TextField(blank = True, null = True) ...
Page: 112 of 196 1 ...
110 111 112 113 114 ...
196
